Description

A DSP server to which a DSP / SSP targeting information mapping method and a DSP / SSP-to-SSP targeting information are mapped, and a DSP server to which a DSP / SSP-

The present invention relates to a DSP / SSP targeting information mapping method and a DSP / SSP targeting information mapping method. More particularly, the present invention relates to a DSP server in which (a) an advertiser server transmits targeting information collected from a user terminal to a DSP server step; (b) mapping the first identifier to the received targeting information by the DSP server; (c) the DSP server transmitting the targeting information to the SSP server; (d) mapping the second identifier to the received targeting information by the SSP server; (e) the SSP server transmitting the second identifier to the DSP server; And (f) further mapping the received second identifier to the targeting information to which the first identifier is mapped by the DSP server, and storing the mapping in the database.

With the development of the communication network and the development of the terminal specification, the communication terminal has become a necessity of the modern person beyond the scope of the conventional simple communication apparatus or information providing apparatus, and has been evolving into a total entertainment apparatus. In addition, communication terminals that can use the Internet provide contents such as advertisement, finance, entertainment, news, and community in various fields.

Especially, most of the means of advertisement delivery through online, which is currently in the limelight, is performed through terminals. Therefore, advertisements made on-line began with a random advertisement on the inventory in the medium. However, since there are many publishers who want to sell advertisements and publishers who want to sell their inventories, there is an advertising agency server for relaying between advertisers and publishers as shown in FIG. 1, The present invention has been developed in such a manner as to expose selected advertisements based on user visit information in the form of FIG.

Retargeting ads are a type of advertising that attracts interested users with high conversion rates through marketing activities, such as search ads, and then exposes the images of products of particular interest to interested visitors through retargeting media. Advertising. This is not an ad type that is simply pop-up or manually viewed when a user visits the Web site, but an advertiser who buys the advertisement to sell the advertisement and sells the advertisement as shown in FIG. 2, Side Platform) server, a publisher that sells inventory to be advertised, and an SSP (Supply Side Platform) server that finds ads to be exposed on behalf of publishers. And sends the advertisement to the identified user terminal.

At this time, the DSP server generates targeting information for each user in advance through data analysis on the sex, age, region, and service usage behavior of the user. Thereafter, the classified advertisement characteristics are classified according to the targeting information, and when the user detects that the user accesses the site of the publisher, the classified advertisement service is provided in such a manner that the classified advertisement is transmitted according to the targeting information of the user.

Meanwhile, when the user accesses the publisher site as shown in FIG. 2, the publisher providing the retargeting advertisement inquires the DSP server about the targeting information about the user and receives a response. The user terminal receives the advertisement registered in association with the targeting information from the DSP server and exposes the advertisement inventory of the publisher accessed by the user.

However, in recent years, the number of publishers that provide retargeting ads has increased, and the number of users connected to each target publisher and the number of accesses per user have been increasing. The number of targeting information inquired by the DSP server managing the targeting information increases as the number of users and the access frequency per service are increased, and the DSP server provides a large amount of targeting information If you do, the traffic you have to deal with increases exponentially. In addition, system performance degradation and advertisement delivery delay time of DSP server are increased.

Therefore, in this specification, instead of an existing retargeting method in which various publishers look up targeting information to a DSP server, one SSP server acting as a publisher can inquire targeting information to a DSP server to propose a method of providing smooth advertisement I want to.

The present invention has been invented based on such a technical background and has been invented to provide additional technical elements which can not easily be invented by a person having ordinary skill in the art, as well as satisfying the technical requirements of the present invention.

With the development of the communication network and the development of the terminal specification, the communication terminal has become a necessity of the modern person beyond the scope of the conventional simple communication apparatus or information providing apparatus, and has been evolving into a total entertainment apparatus. In addition, communication terminals that can use the Internet provide contents such as advertisement, finance, entertainment, news, and community in various fields. Especially, most of the means of advertisement delivery through online, which is currently in the limelight, is performed through terminals.

1 is a configuration diagram of a conventional advertisement providing system including an advertisement agency server for relaying between an advertiser and a publisher according to the related art.

In the first form of online advertising, advertisers and publishers (400) directly deal with advertisements and inventory without an ad agency. However, as the number of Internet users increases, the effect of Internet advertising increases dramatically. There have been a lot of publishers who want to sell their inventory. As shown in FIG. 1, an advertising agency server for advertising and inventory transactions between advertisers and publishers appeared. This method is a method in which random advertisement is exposed to the inventory in the medium. Then, based on the visit information of the user, the user is identified according to the user's access and the advertisement is selectively selected based on the user's information, Advertising was developed.

Retargeting ads are a type of advertising that attracts interested users with high conversion rates through marketing activities, such as search ads, and then exposes the images of products of particular interest to interested visitors through retargeting media. Advertising. This is not an ad type that is simply pop-up or manually viewed when a user visits the Web site, but an advertiser who buys the advertisement to sell the advertisement and sells the advertisement as shown in FIG. 2, Side Platform) server, a publisher that sells inventory to be advertised, and an SSP (Supply Side Platform) server that finds ads to be exposed on behalf of publishers. And sends the advertisement to the identified user terminal 10. The system of FIG.

At this time, the DSP server generates retargeting advertisements for the targeting information on a user-by-user basis by analyzing data on the information of browsing a specific page in the website visited by the user, the shopping cart history of the visited user, login information, Thereafter, the classified advertisement characteristics are classified according to the targeting information, and when the user detects that the user accesses the site of the publisher, the classified advertisement service is provided in such a manner that the classified advertisement is transmitted according to the targeting information of the user.

FIG. 2 is a diagram illustrating a method of providing a retargeting advertisement by querying targeting information through a DSP server 200 directly by a publisher in a conventional retargeting advertisement service.

Referring to FIG. 2, when a user accesses a publisher site in a conventional method of detecting a user, a publisher providing a retargeting advertisement receives a response by inquiring a DSP server about targeting information on the user. The user terminal receives the advertisement registered in association with the targeting information from the DSP server and exposes the advertisement inventory of the publisher accessed by the user.

However, in recent years, the number of publishers that provide retargeting ads has increased, and the number of users connected to each target publisher and the number of accesses per user have been increasing. As a result, the number of target publishers that send out retargeting advertisements increases, the number of users per service and the frequency of access increases, the number of targeting information inquiries that are displayed on the DSP server managing the targeting information increases, and the DSP server provides a large amount of targeting information If you do, the traffic you have to deal with increases exponentially. In addition, system performance degradation and advertisement delivery delay time of DSP server are increased.

Therefore, in this specification, instead of the conventional retargeting method in which various publishers inquire targeting information to a DSP server, one SSP server acting as a publisher can inquire targeting information to the DSP server, thereby reducing burden on the DSP server We propose a method of providing advertisement.

Before describing various embodiments of the present invention, terms used in the present invention will be defined as follows.

Retargeting Ads is a product that has experience of visiting an advertiser's website or has experienced viewing a specific page within the website, Or a method of showing an advertisement for a service again.

In this case, the targeting information means information used by a user who visited the advertiser's web site to select an advertisement considering an action taken in the advertiser's web site. Therefore, information that a specific page is browsed within the website visited by the user or a shopping cart history of the user who visited, login information, and the like can be the targeting information.

Media refers to media through which advertisements are exposed to users. For example, TV, radio, and the Internet are the means by which advertisements can be exposed. The present invention is directed to a retargeting advertisement on-line, and the Internet can be a medium.

Inventory means the space in the medium where the advertisement is exposed. In the case of the Internet, inventory can be a specific space for placing advertisements on a website.

An advertiser is someone who wants to buy inventory that will show ads to show their ads.

A publisher is a person who has an inventory in the medium where the advertisement can be placed.

A demand side platform (DSP) server is a server that is managed by a vendor looking for an appropriate inventory to advertise on behalf of an advertiser.

A supply side platform (SSP) server is a server managed by a vendor who sells inventory on behalf of publishers and seeks ads to be exposed.

FIG. 3 is a reference diagram for simplifying interworking between respective components to illustrate a DSP / SSP targeting information mapping method according to an embodiment of the present invention, FIG. 4 is a flowchart for explaining a DSP / to be.

3 and 4, a method for mapping information between DSPs / SSPs according to an embodiment of the present invention includes the steps of (a) transmitting targeting information collected by the advertiser server 100 from a user terminal 10 to a DSP server 200 (S410); (b) mapping the first identifier to the received targeting information by the DSP server 200 (S420); (c) the DSP server transmits the targeting information to the SSP server 300 (S430); (d) mapping the second identifier to the received targeting information by the SSP server (S440); (e) the SSP server 300 transmits the second identifier to the DSP server 200 (S450); And (f) mapping the second identifier received from the DSP server 200 to the targeting information mapped with the first identifier and storing the mapped target information in the database (S460).

In step S410, the advertiser server 100 transmits the targeting information collected from the user terminal 10 to the DSP server 200. In step S410, The user terminal 10 can manage targeting information serving as a reference of a retargeting advertisement service by including it in a user cookie. When the user accesses the website of the advertiser, the advertiser server 100 may transmit the targeting information to the DSP server 200 by reading the user cookie including the targeting information. Thereafter, when the user terminal 10 accesses the website of the publisher 400 managed by the SSP server 300 contracted with the DSP server 200, a retargeting advertisement mapped to the targeting information is received And provide it to the user.

Here, the targeting information may include at least one of targeting information, login information, IP address, page information viewed by the user, information of the interested goods of the user, and purchase details of the user. Accordingly, when the user views the 'A bed' in the advertiser server 100 or stores the 'A bed' in the shopping cart, this targeting information is stored in the cookie of the user terminal 10, 200). Then, when the user accesses the website of the publisher 400, the DSP server 200 can realize the re-targeting service by providing 'A bed' related advertisement based on such targeting information.

The user terminal 10 may be a mobile phone, a PDA (Personal Digital Assistant), a cellular phone, a PCS (Personal Communication Service) phone, a GSM (Global System for Mobile) phone, a W- (PDAs), CDMA-2000 phones, Mobile Broadband System (MBS) phones, Portable Multimedia Player (PMP), Mobile Internet Device (MID), Smart Phone, Desktop, Tablet PC, Note books, net books and information communication devices. On the other hand, the user terminal 10 may represent a portable small device, but it may be referred to as a mobile communication terminal when it includes a camcorder or a laptop computer, so that the embodiment of the present invention is not particularly limited thereto.

In step (b), the DSP server 200 maps the first identifier to the received targeting information. The first identifier is used to distinguish the targeting information of each user from the identifier given by the DSP server 200 for managing the user targeting information, and when the advertisement request of the SSP server 300 is received, And can be used to selectively provide retargeting advertisements.

In step (c) (S430), the DSP server 200 transmits targeting information to the SSP server 300. The DSP server 200 and the SSP server 300 should be able to recognize that the user who is connected to the advertiser server 100 to provide the retargeting advertisement is the same user when accessing the website of the publisher 400. [

The publisher 400 searches the DSP server 200 for the targeting information for the user and receives a response from the advertiser server 100. In this case, That the same user who accessed the publisher 400 accessed the publisher's Web site.

However, since the number of the publishers 400 providing the advertisement is greatly increased, a great number of the publishers 400 request the inquiry to the DSP server 200 and the DSP server 200 transmits the advertisement to each of the publishers 400 The DSP server 200 has a higher cost to prevent traffic on the DSP server 200 side and the DSP server 200 exponentially increases the traffic to be processed in the case of providing a large amount of targeting information, System performance degradation and advertisement delivery delay time of the server 200 are increased.

Accordingly, the present invention attempts to solve the burden of the DSP server 200 by presenting a new method of recognizing the same user when the user connected to the advertiser server 100 accesses the website of the publisher 400.

Therefore, according to the present invention, when a user who is connected to the advertiser server 100 through information transmission / reception between the DSP server 200 and the SSP server 300 recognizes the same user when accessing the website of the publisher 400, In step (c), the targeting information of the user managed by the DSP server 200 is transmitted to the SSP server 300. In this case, the transmission target information may be information that allows the SSP server 300 to identify the user who accesses the website of the publisher 400.

The DSP server 200 transmits the second identifier including the return URL address to be returned to the SSP server 300 in step (c) (S430). This may be the address of the DSP server 200, more specifically, the database address of the DSP server 200 storing the same targeting information that the SSP server 300 maps to the second identifier. Therefore, the SSP server 300 can transmit the second identifier directly mapped to the database address of the DSP server 200 storing the targeting information, and the DSP server 200 receives the second identifier, The second identifier can be directly mapped to the mapped targeting information, so that intuitive targeting information management becomes possible.

In step (d) S440, the SSP server 300 maps the second identifier to the received targeting information. The second identifier is used to distinguish the targeting information of each user from the identifier given by the SSP server 300 in order to manage the user targeting information. When the publisher 400 selects the target of the user who accesses the website of the publisher 400 Information is read from the SSP server 300 and there is an advertisement request in the SSP server 300, the DSP server 200 can quickly retrieve user's targeting information and request a retargeting advertisement to the DSP server 200 managing the user.

In step (e) (S450), the SSP server 300 transmits the second identifier to the DSP server 200. This is to inform the DSP server 200 of the identifiers managed by the SSP server 300 because the identifiers managed by the servers are different. Each server can distinguish the information managed by its own server and can manage it by giving an identifier for each piece of information for quick retrieval when necessary or for security reasons. For example, when the ID of the user is 'banana', it is possible to manage a specific identifier such as 'banana = bbb' according to predetermined rules in each server, Banana = aaa ', but the SSP server 300 can manage the same user targeting information by assigning different identifiers such as' banana = bbb'. Therefore, in the present invention, the SSP server 300 provides the second identifier mapped to the user targeting information managed by the SSP server 300 in advance to the DSP server 200. If the advertisement request is subsequently transmitted from the publisher 400, The DSP server 200 manages the first identifier managed by the DSP server 200 in the SSP server 300 according to a method to be described later by providing the second identifier to the DSP server 200 As soon as the advertisement request is received from the SSP server 300, the targeting information mapped to the second identifier can be quickly searched for and a retargeting advertisement can be provided because it is previously mapped with the second identifier.

In step (f) (S460), the DSP server 200 may further map the received second identifier to the targeting information to which the first identifier is mapped, and store the mapping in the database. The DSP server 200 receives the targeting information from the advertiser server 100, maps the first identifier to the SSP server 300, and transmits the targeting information to the SSP server 300, 2 identifier, and additionally maps and stores the second identifier in addition to the targeting information to which the first identifier is mapped.

For example, if the ID of a specific user is 'banana', the DSP server 200 stores 'banana = aaa' and transmits the ID 'banana' of the user to the SSP server 300, and the SSP server 300 quot; banana = bbb " and informs the DSP server 200 of the second identifier. Then, the DSP server 200 maps the first identifier and the second identifier, such as 'banana = aaa = bbb', and stores the same in the database. Thus, as in the embodiment of the method for providing the retargeting advertisement described later, The SSP server 300 can recognize that the connected user is the same user when accessing the web site of the publisher 400.

Here, the database is a device for storing data, and basically stores data such as environment variables for searching, sorting, analyzing, etc. Such a database function can be implemented by using a normal technology, It is omitted.

As described above, the first identifier managed by mapping with the targeting information in the DSP server 200 and the second identifier managed in the SSP server 300 by mapping with the targeting information are mapped to the same targeting information, Instead of the existing retargeting method in which the target server 400 queries the DSP server 200 for targeting information, one SSP server 300 acting as a publisher 400 queries the DSP server 200 for targeting information It is possible to smoothly provide a retargeting advertisement.

Meanwhile, it is preferable that the user terminal 10, the advertiser server 100, the DSP server 200, the SSP server 300, and the publisher 400 transmit and receive information through the communication network. The communication network includes a base station controller, a base station transmitter, and / or a repeater. Here, the base station controller relays signals between the base station transmitter and the exchange. The network supports both synchronous and asynchronous. Therefore, in case of the synchronous type, the transmission and reception base station transmitter will be a base station transmission system (BTS), the transmission and reception base station controller will be a base station controller (BSC) The transmitting and receiving base station controller will be an RNC (Radio Network Controller). Of course, the communication network according to the embodiment of the present invention is not limited to this, and it can be said that the communication network can be used for a GSM network other than a CDMA network and an access network of a next generation mobile communication system to be realized in the future.

The communication network may further include an access point. The access point represents a small base station such as a femto or pico base station, which is installed in a large number of buildings. Here, the femto or pico base station is classified according to the maximum number of mobile terminals 110 that can be connected on the classification of the small base stations. The access point also includes a user terminal 10 and a local communication module for performing local communication such as Wi-Fi. The short-range communication is not limited to Wi-Fi, but may be variously applied to a variety of applications such as Bluetooth (Radio Frequency) and UWB (Ultra Wide Band) communication such as Bluetooth communication, zigbee communication, IrDA, UHF and VHF Standard. The access point may extract the location of the data packet, specify the best communication path to the extracted location, and forward the data packet to the next device, e.g., the user terminal 10, along the designated communication path. Access points can share multiple lines in a typical network environment.

An access point is largely divided into a fixed access point and a mobile access point. The fixed access point may include a router, a repeater and a repeater, and the mobile access point may include a bridge product of a particular manufacturer, such as a KT egg. Such a mobile access point can read the receiving side address from the transmitting side information and specify the most appropriate communication path and transmit it while ensuring free mobility.

FIG. 5 is a simplified schematic view illustrating a method of providing a retargeting advertisement using a DSP / SSP targeting information mapping method according to an embodiment of the present invention. FIG. 2 is a flowchart illustrating a method of providing a retargeting advertisement using an inter-targeting information mapping method.

5 and 6, a method for providing a retargeting advertisement according to an embodiment of the present invention using the DSP / SSP inter-targeting information mapping method includes the steps of (a) A step S610 of requesting advertisement while transmitting one targeting information to the SSP server 300; (b) the SSP server 300 requests an advertisement while transmitting a second identifier mapped to the received targeting information to the DSP server 200 (S620); (c) a step (S630) for the DSP server (200) to search for a first identifier mapped to the transmitted second identifier and to extract targeting information from the database; (d) selecting the advertisement based on the extracted targeting information by the DSP server 200 and transmitting the selected advertisement to the SSP server 300 (S640); And (e) transmitting the advertisement received by the SSP server 300 to the publisher 400 (S650).

In step (a) S610, the publisher 400 requests the advertisement while transmitting the targeting information collected from the user terminal 10 to the SSP server 300. The user terminal 10 can manage targeting information serving as a reference of a retargeting advertisement service by including it in a user cookie. When the user accesses the website of the publisher 400, the publisher 400 may request the advertisement while reading the user cookie including the targeting information and transmitting the targeting information to the SSP server 300.

The publisher 400 reads the targeting information of the user terminal 10 when the user accesses the website of the publisher 400 and inquires the DSP server 200 about the targeting information about the user, That the user who has connected to the advertiser server 100 has accessed the website of the publisher 400. [

Accordingly, the present invention does not directly transmit the targeting information to the DSP server 200, but transmits the targeting information to the SSP server 300 as in step (a) The connection between the publisher 400 and the DSP server 200 for recognizing the user is simplified and the burden of the DSP server 200 is solved.

Herein, the targeting information may include at least one of targeting information, login information, IP address, page information viewed by the user, information of the interested goods of the user, and purchase details of the user. It may be information that the server 300 can identify the user who accessed the website of the publisher 400.

Therefore, when the user accesses the advertiser server 100 and browses the product before accessing the website of the publisher 400, the advertiser server 100 transmits targeting information for identifying the user of the user terminal 10 to a cookie When the user accesses the website of the publisher 400, the publisher 400 reads the targeting information to the cookie of the user terminal 10 and provides the targeting information of the user to the SSP server 300, The SSP server 300 transmits a second identifier mapped to the targeting information to the DSP server 200. The DSP server 200 searches the targeting information mapped with the received second identifier, The advertiser can realize the re-targeting service by providing the advertisement related to the advertisement.

In step (b), the SSP server 300 transmits a second identifier mapped to the targeting information transmitted to the DSP server 200, and requests advertisement. In other words, in identifying a user to provide a retargeting advertisement requested by a large number of publishers 400, a large number of publishers 400 may not directly request the user to identify the user to the DSP server 200, The SSP server 300 integrates the query of the publisher 400 and transmits the query to the DSP server 200 to reduce the traffic generated in the DSP server 200 and to provide the search advertisement smoothly have.

In step (c) (S630), the DSP server 200 searches for a first identifier mapped to the received second identifier, and extracts targeting information from the database. The second identifier managed by the SSP server 300 and the first identifier managed by the DSP are generally different from each other. This is because each server distinguishes the information managed by its own server and searches for it when necessary, or manages an identifier for each information for security reasons.

For example, when the ID of the user is 'banana', it is possible to manage a specific identifier such as 'banana = bbb' according to predetermined rules in each server, Banana = aaa ', but the SSP server 300 can manage the same user targeting information by assigning different identifiers such as' banana = bbb'. Therefore, in the present invention, the SSP server 300 provides the second identifier mapped to the user targeting information managed by the SSP server 300 in advance to the DSP server 200. If the advertisement request is subsequently transmitted from the publisher 400, The DSP server 200 manages the first identifier managed by the DSP server 200 in the SSP server 300 according to a method to be described later by providing the second identifier to the DSP server 200 As soon as the advertisement request is received from the SSP server 300, the targeting information mapped to the second identifier can be quickly searched for and a retargeting advertisement can be provided because it is previously mapped with the second identifier.

Accordingly, upon receiving the second identifier for identifying the user connected to the publisher 400 from the SSP server 300, the DSP server 200 can quickly search for the first identifier mapped to the second identifier, Information can be extracted from the database.

The step (d) S640 selects an advertisement based on the targeting information extracted by the DSP server 200, and transmits the selected advertisement to the SSP server 300. Accordingly, when the user views the 'A bed' in the advertiser server 100 or the 'A bed' in the shopping cart, the advertiser server 100 transmits the targeting information including the details viewed from the advertiser server 100, The DSP server 200 stores the targeting information and then accesses the website of the publisher 400. The DSP server 200 recognizes the user by the process described above , It can extract the advertisement for 'A bed' based on the previously stored targeting information and transmit it to the SSP server 300.

In step (e) (S650), the SSP server 300 transmits the advertisement received from the DSP server 200 to the publisher 400. Therefore, instead of the publisher 400 sending a direct user identification request and an advertisement request to the DSP server 200, the SSP server 300 integrates the requests of the various publishers 400 and transmits and receives information to and from the DSP server 200 It is possible to provide the retargeting advertisement smoothly without burdening the DSP server 200 over the conventional retargeting advertisement method.

Meanwhile, in step (e) (S650), if there is no first identifier mapped to the second identifier in step (d), the advertisement is selected without considering the targeting information. There is a case where no targeting information exists in the DSP server 200 or the SSP server 300 for these users because all users connecting to the publisher 400 are not from the advertiser server 100. [ In this case, the publisher 400 reads the cookie of the user terminal 10 to request the advertisement to the SSP server 300, but since the SSP server 300 and the DSP server 200 do not have the targeting information for the user, Ads can be selectively provided.

7 is a flowchart illustrating a method of mapping DSP / SSP targeting information between the DSP server 200 according to an exemplary embodiment of the present invention.

Referring to FIG. 7, a method of mapping the DSP / SSP targeting information between the DSP server 200 according to an embodiment of the present invention includes the steps of (a) receiving the targeting information from the advertiser server 100 (S710) ; (b) mapping the first identifier to the targeting information (S720); (c) transmitting the targeting information to the SSP server 300 to receive a second identifier mapped to the targeting information from the SSP server 300 (S730); And (d) further mapping the second identifier to the targeting information to which the first identifier is mapped and storing the mapped target information in a database (S740).

In step (a) (S710), the DSP server 200 receives the targeting information from the advertiser server 100. When the user accesses the advertiser's web site, the advertiser server 100 may transmit the targeting information to the DSP server 200 by reading the user cookie including the targeting information. Thereafter, when the user terminal 10 accesses the website of the publisher 400 managed by the SSP server 300 contracted with the DSP server 200, a retargeting advertisement mapped to the targeting information is received And provide it to the user.

In step (b) (S720), the DSP server 200 maps the first identifier to the targeting information. The first identifier is used to distinguish the targeting information of each user from the identifier given by the DSP server 200 for managing the user targeting information, and when the advertisement request of the SSP server 300 is received, And can be used to selectively provide retargeting advertisements.

In step (c) (S730), the DSP server 200 transmits the targeting information to the SSP server 300 and receives the second identifier mapped to the targeting information from the SSP server 300. The DSP server 200 and the SSP server 300 should be able to recognize that the user who is connected to the advertiser server 100 to provide the retargeting advertisement is the same user when accessing the website of the publisher 400. [

Also, the step (c) S730 may include transmitting the second identifier from the SSP server 300 including the Return URL address to which the DSP server 200 returns the response. This may be the address of the DSP server 200, more specifically, the database address of the DSP server 200 storing the same targeting information that the SSP server 300 maps to the second identifier. Therefore, the SSP server 300 can transmit the second identifier directly mapped to the database address of the DSP server 200 storing the targeting information, and the DSP server 200 receives the second identifier, The second identifier can be directly mapped to the mapped targeting information, so that intuitive targeting information management becomes possible.

In step (d) (S740), the DSP server 200 further maps the second identifier to the targeting information to which the first identifier is mapped, and stores the mapping in the database. The DSP server 200 receives the targeting information from the advertiser server 100, maps the first identifier to the SSP server 300, and transmits the targeting information to the SSP server 300, 2 identifier, and additionally maps and stores the second identifier in addition to the targeting information to which the first identifier is mapped.

8 is a flowchart illustrating a method of providing a retargeting advertisement by the DSP server 200 according to an embodiment of the present invention.

Referring to FIG. 8, a method of providing a retargeting advertisement by the DSP server 200 according to an embodiment of the present invention includes the steps of: (a) receiving, from the SSP server 300, Receiving an advertisement together with the information (S810); (b) searching (S820) for a first identifier that is mapped to the second identifier; (c) extracting the targeting information mapped with the first identifier from the database (S830); And (d) selecting an advertisement based on the extracted targeting information and transmitting the advertisement to the SSP server 300 (S840).

In step (a) (S810), the DSP server 200 receives an advertisement together with the second identifier information mapped to the targeting information on which advertisement is to be provided from the SSP server 300. In other words, in identifying a user to provide a retargeting advertisement requested by a large number of publishers 400, a large number of the publishers 400 may not directly request the user to identify the user to the DSP server 200 as in the conventional method, The SSP server 300 acting as an agent of the ISP 400 integrates the query of the publisher 400 and transmits the query to the DSP server 200 so as to reduce the traffic generated in the DSP server 200, Can be provided.

In step (b) (S820), the DSP server 200 searches for a first identifier mapped to the second identifier. The second identifier managed by the SSP server 300 and the first identifier managed by the DSP are generally different from each other. This is because each server distinguishes the information managed by its own server and searches for it when necessary, or manages an identifier for each information for security reasons.

However, in the present invention, since the DSP server 200 stores the target information including the second identifier managed by the SSP server 300, the first identifier and the second identifier are mapped together in the targeting information for one user, .

Accordingly, immediately after the DSP server 200 receives the second identifier for identifying the user connected to the publisher 400 from the SSP server 300, the DSP server 200 searches the first identifier mapped to the second identifier quickly (c) (S830), the DSP server 200 can extract the user's targeting information from the database.

In step (d) (S840), the advertisement is selected based on the targeting information extracted by the DSP server 200 and is transmitted to the SSP server 300.

For example, if the user views the 'A bed' in the advertiser server 100 or the 'A bed' in the shopping cart, the advertiser server 100 stores the targeting information including the details viewed by the advertiser server 100 The DSP server 200 stores the target information in the DSP server 200. If the DSP server 200 accesses the website of the publisher 400 in the future, the DSP server 200 acquires the user And extracts an advertisement for 'A bed' based on the previously stored targeting information, and transmits the extracted advertisement to the SSP server 300.

Therefore, instead of the publisher 400 sending a direct user identification request and an advertisement request to the DSP server 200, the SSP server 300 integrates the requests of the various publishers 400 and transmits and receives information to and from the DSP server 200 It is possible to provide the retargeting advertisement smoothly without burdening the DSP server 200 over the conventional retargeting advertisement method.

Hereinafter, the DSP server 200 to which the DSP / SSP targeting information of the present invention is mapped from the device perspective will be described.

The DSP server 200 to which the DSP / SSP inter-targeting information according to the embodiment of the present invention is mapped receives the targeting information from the advertiser server 100 and transmits the targeting information to the SSP (Supply Side Platform) A communication unit for receiving a second identifier mapped with the targeting information from the SSP server 300; a mapping unit for mapping the first identifier to the targeting information received from the advertiser server 100; A database for storing targeting information to which the first and second identifiers are mapped, and a database for storing the second identifier when the advertisement request is received together with the second identifier from the SSP server 300, A first identifier and a targeting information mapped to the identifier are extracted from the database and the advertisement is selected based on the extracted targeting information to transmit the advertisement to the SSP server 300 It may contain.

Here, the targeting information may include at least one of login information, an IP address, page information viewed by the user, information of the interested goods of the user, and purchase details of the user. The controller may select the advertisement without considering the targeting information if the first identifier is not mapped to the second identifier.
